i Y Application mea' Maren 22, 1924. serial No. 7o1,os2."i

The object of my invention is a reduction in the time required to windarmatures of all numbers of oles including both externally and internaly (stator) wound armatures. The word armature will herein be used toinclude all these kinds.

My object is further to enable the winding of the wire directly onmultipolar armatures both external and internal instead of the ordinarymethods of winding coils and then assembling them in the slots.

Further objects are the production of layer windings; the elimination oftooth interference; the handling of coarse wire, the provision of meansfor manipulating the leads as well as protecting the insulation; animprovement in indexing devices and in armature holding chucks.Applications to bipolar and four ole externally wound armatures only ares own, being deemed sufficient for disclosure. A

This invention may be considered as allied to and the outgrowth of anumber of my previous inventions which will be mentioned at appropriatelaces. The special terminology develope therein will be adheredto.

In thedrawings Figure 1 is a perspective of this invention applied toafour pole armature which requires mounting" in a lathe having head andtail stock (similarly to that disclosed in my Patent #874,163 onmultipolar armature winding machines). The shafts 13 and 14 beingportions of said lathe, the armature is supported on a conventionalchuck 15 which in addition may carry the lead handling devices.

Three sets of wire directing'guides being carried on the turret 16, forin this machine I prefer to use distinct sets for different coils ratherthan combined as in the said patent. Figure 2 is'a view of the windingknuckle B11 which is on the concealed side of the Winding head oppositeT1. l

One of the problems involved in winding multipolar armatures is that anywire wound into the slots has a tendenc to wind against the teeth whichthe coil enc oses, but in order to fill the slots with more than onetierof wire i. e., more thanone turn per layer.. it is necessary'thatthe 'wire be offset that is, after it is lintroduced into the slotopening plan offthe leadlsetter.:V

llolfpyagwclirxntypeY it be'forced up and away from the teeth aroundwhich it is being wound, and "into place,-in other words forced upwardsagainst.

the tension on the winding-wire. Those.`=

wires laying at right angles tothe depths of the slots will beconsidered as in layers, while those wires which lay approximatelyparallel with the depths of the slots as in tiers.

In my patent on ofsetters #1,351,230 (hereinafter referred to `as theoifsetter patent), I have shown It'was shown applied onl to the trailingcorners-of the slots. In this application I disclose means for use inconjunction with these oifsetters at the entering corners, therebyobtaining the rather surprising (as no turn by turn feeds are used)layer forming characteristics on these corners as well as the trailingcorners. At the same timeI overcome anothery diliiculty in windingarmatures Aparticularly evident' onr multipolar armatures both externaland internal, which is the interference of the teeth 18 (next externalto the coil) with the .wire going into the slots. It is necessary inorder that the wire go in the slots without injury by these teeth and toaid the entering oii'setter that thewire at thev entering corner 19 ofthe slot be held out thereof until the slot filling wire W assumes aposition that will enable its being put into the slot without injuryfrom the said teeth.

It is of course desirable that wire kinking guards an`d time killingdevices be done away with. I am able to accomplish these 110 means foroffsetting.

, `the top of the slots.

' location physically with reference thereto and shows that itisiintended for winding in the bottom of the slot.

Figure 9 is an angle view of the entering linger 9. Figure 10 is anelevation showing the4 relation of the said finger to the slot 20, andrevealing that it is intended to wind in Figure 11 being a lan view ofthe same finger. On each one o the wire directing guides or windingfingers as I shall hereinafter call them at the entering corners,numbers 1, 5, 7 and 9 shown in .the drawings and 3 and 11 which are onthe op' Asitejside of the machine, I provide a `which becomes 'a curveAho din surface 21 on which the Winding wire is shown impinged in Figure1 this surface isplaced at such an angle that it holds the windin wireout of the slot until the winding'mac ine has turned to a positionrmitting its passage into the slot without injur vby the teeth. At thisposition the wire irecting or as I shall call it, driving'surface 22,comes into lay, overcomes the effect of the holding sur ace, 21, forcingthe wire W over the ofi'setter 23 and into the slot'. 4

The action of holdin driving and offsetting are so intermingle thatinstead of distinctly occurring on the holding, driving and offsettingsurfaces they seem to occur more on the transition surface 24 whichconnects the'said surfaces. u

At the final delivery of the turn from the winding finger additionaldelivering action is sometimes required, .this I supply by the deliverysurface, (angle or curve) 25 which has an influence quitedisproportionate to its B126.

Fi s 12 and 13 are elevation and plan of a trailing finger 12 thedelivery surface 26- on uite extensive as compared with the deliveringsurface 25 on the entering finger. ,It has an oisetter 27 whose actionis practically the same as that described in my osetter patent and neednot .l bedescribed further than to say that associated with itis aninsulation protection Vfin- 'ger 28 and coil forming foot 29. Thetrailing fingers are numbered 2, 4, 6, 8,l 10 (not shown) and 12.

The second method is illustrated in Figure 18 which shows it inconnection with my adjustableelicpolar drum armature winding machine hwhich has been the .subject of other patents and applications. It is ofpossibly more value on bipolar than on multipolar armature windingmachines.

To this head I apply what I call a worm offsetter A (B bein a duplicatethereof) which is placed in t e path of the winding wire W as shown attheentering corner of the slot Cy this Worm is: driven preferably bymeans of a gear D on its shaft vwhich latter ma be fitted with gimbaljoints E, this gear Ameshes with the stationary gear F that is attachedto the stationary means for supporting the winding head, as the motorframe G. A very good ratio between these gears is two to one, I

The action of this device is as follows: When the windin machinerevolves the wire W impinges 'on t iel worm A and is held out of theentering end C of the slot until the wire assumes substantialparallelism with the said slot, at which time the rotation of the worm'carries the said wire outwardlyV against the winding tension until itis delivered,'or delivered to the offsetting surface H of the worm overwhich it will slip to the far side of the slot in a substantiallysimilar manner to the rigid offsetter on the other end of the slot, asdescribed in said ofsetter patent.

Where conditions are favorable I may disuse with the lead of the worm,makin it 1n the form of a groove or I ma even ispense with the groovealso, allyowing the winding wire to impinge on what would then be asmooth surface, the motion of `which would then bring the ofsettersurface H into play and discharge the Wire over it,

or I may-dispense with the offsetting surface and use the worm only.

When pro erly proportioned both methods and especial y when combinedwith ofisetters at the other end of the slot will produce level windingsor windings that are even beyond level and put the wire in layerschangin the number of turns in the layer as the width-of the slotchanges.

In multipolar armature winding whether external or internal, the strainor pullof the windingwire comes very largely against the corners of thearmature teeth, whereas in bipolar armatures the winding strain comes toa far greater extent directly on the bottom of the slots. This strainhas a tendency to distort the teeth of the armature core particularlythe rather soft libre punchings that are usually placed on the endthereof, and what is still worse to cut throughthe slot insulation andground the windings as is much more apparent on coarser wires than onfine. To overcome this difficulty I provide, insulation protectinlingers 28 shown attached to the winding ers 1 to 12 which assumedifferent lengths, ferent roportions and even different shapes, tot emost of the strain of the wire off the corners of the slots. One of thevariations in form referred to will be noticed at 28 Figures 6 and 8where the tip end of the finger 28 is shown with a slight hook thisparticular type of finger finds its greatest usefulness on coils whichgo in the bottom of the slots the hook then tak` ing the winding strainoff the bottom? edges thereof. The term corner of the slot will betakento include both the side and the bottom cor-` ners. Where the 4wire iswound in the tcp of the slots the fingers may of course be com-'paratively short-er as in Fifrures 9, 10, 11 and, the hook would then beundesirable.

These insulation protecting fingers when of proper proportions are soeffective that* armatures may actually be wound without fibreendfpunchings and still not have an undue proportion of grounds or breakdowns later on. Y f

These insulation protecting fingers .are quite different from the shortfingers or beards which I have all my winding maciiines for carrying theuire past the overhanging corner of the' s ot.

The presence of these insulation protecting fingers particularly whencombined with may armature indexing dog present. an a ditional problem,for they will interfere with the previous coil when positioning thewinding machine for winding the next coilld To overcome this difficultyI prefer'to mount some or all the windin fingers on hinge pins 31 with aspring 32 or holding them 1n a clearance position (Figure 1 at 5)andallowing them to4 automaticallyA assumethef winding position (Figure1 at 1) when thcl winding wire W is encountered.

The surface 29 carried by the forming fingers or more accurately by theoffsetters, I shall call a forming foot for when formed correctly itplays a very marked part in the formation of the top of the coil thelast layer thereof being wound between it and the preceding layer thusproviding a positive means for the smooth winding thereof in addition tothe layer forming characteristics of other parts.

A problem not encountered in winding biolar armatures that isencountered in winding multipolar armatures is the formation of the endsof the coils i. e. the head of the armatures winding. For fine-wire thearts S shown in my Patent 874,163 accomplished this object very neatly,the wire being slipped over the angular surface thereof until it came torest upon thelantl at the bottom end.

For coarse wire armatures such as this application is more particularlyconcerned with I have discovered a. far better method of accomplishingthe same end.

I shall call the coil end forming parts T,

`T2, Ta and Bt, B, B?, Figures 1, 2, 3, 4 and 5 knuckles as this termhas come into rovided in practically universal use in connection withparts of coil formin apparatus which have todo with the en s o thecoils. 1

In nearlyall forms of multipolar 4armature winding either external orinternal the succeeding coilsI nestl with each other, the lower orleading half of the coil end 33 lying over the same part of thepreceding coil, the upper'half of the coil end 34 lying inside of thesame art of the preceding coil, as it were, over anging 35. In order toeconomize space the lower half of the armature coil 33 should be wounddirect] on the same part of the precedin coil. oaccom lish this I referto provi( e a coil forming c eek 36 which for convenience of adjustmentprefer to affix to a` knuckle. ,This cheek when of the proper shape willform the art of the coil end 33 laying over the rece ing coil as wellals the extreme tip end thereof 37.

This arrangement supports one half of the coil end during windlng. Theother half on the inside nesting or overhanging art of the coil end 35is best supported by a ractional end form 38 which in the'case of theparticular armature illustrated Works best when it assumes a formsimilar to the said overhanging part of the coil end as shown at 35,Figure 14.

This fractional end form will hereinafter be referred to as a knucklefinger. Conf sidering the smallness of this finger its effect in formingthe end of the coils is great.

For forming the first coil and other special positions I have found itdesirable to rovide a land 39 on the tip end of the lnuckle finger 38 toprevent the first turns of the first coil (which has no coil back of itfor support) from dropping off of this finger and winding directlyagainst thearmature head, the proportions of-this land. 39 vary quiteconsiderably according to the severity of the duty im osed thereon. InFigure 2 showing knuck e B1 this land assumes the sha e of aconsiderable hook shown on Bl an behind it for retaining other turns.

actually requires a secondary land 39A Owing to the different positionof the u duce the land thereon to only a suggestion I of a hook.

Under some conditions I find it desirable to offset the windin wire Wnot only in the slots but also onl te coil ends for by this means thelay of the turns on the ends may be made ymore continuous andsymmetrical with the wire in the slots. In the particu lar machine usedfor illustration this is donc on the last coil by the offsetting lug 17applied to knuckle B3 which because it is on the fa-l side of themachine opposite T3 is separately illustrated in Figures 3, 4, 5. Myoffsetter atent above, mentions the use of offsetters or coil forming,some of the izo ` the spring` 43.

combinations with them herein are however new.

As the wound coils always have a tendenc to loosen up when released,interfering wit 1 succeeding coils I have found it convenient to.provide presser foot 40 to hold them in place whilethe succeeding coilsare wound, as a matter of convenience only I have applied them to allknuckles although they may e separate. Y

Mymachinery for winding the wire into the slots of the armature havereduced the time of winding'to such an extent that lead handling mayreadilygtake `far more time thanavinding thearmature. In this inventionI overcome some 'ofthis lost 'time Aas OHOWS! 'i kIt isvdesirable toconnect the lower leads ofa multipolar armature as it is wound, and as`the leads 40 of the most prevalent typefof" multipolar armatureyconnections point awa fromfthe coil'they are of necessity outV rom underr the. influence of any device -which places the wire of the coil'in theslots and therefore do not automatically fall into the slotiand inaddition make a rather sharp bendo'ver the corner of the slot withresultant liability of grounding. Also owing to the 4elasticity of thewinding wire, the property copper has of giving under a 'continuedstrain, and the reaction of succeeding coils, by the time the last coilsare ready to be placed on over the first, the first coils are verylikely to have stpread out and to occupy a greater portion o the slotsthan necessary.

I overcome these three difiiculties by the use ofthe parts42 which Ishall call a lead layer, Vwhich lis at once, a lead layer, for guidingthe lead intoV the slot and laying itat a proper point, a lead holder,holding the lead in such a position that the corner of the slot islargely relieved of the tension of the winding' wire obviating groundsat this point, and a coil press. I press the first coils back into placeby means of the presser foot 42 on the lead layer 42 and The necessityfor this presser foot is due 4to the fact that these first coils` do notcome under the influence of the knuckles.

In operation: the lead wire after it is secured to the commutator orotherwise will, be automatically guided into place by the lead la 7ersurface 44 requiring no attention from t e operator, and will be held inplace by the bottom .end thereof. l

After the coil has been wound it is desirable that the ,upper leads beheld straight out and usually not best to connect them as the Windingproceeds. To accomplish this I may provide a snubbing pin or moreaccurately snubbing hook 45 which I prefer to make in the form of aninverted hook presser feet on the necesa:

having a long` point suitable for use as a guide for directing the leadwire into the ook when the winding machine is reversed. By making thisdevice asshown the top lead will be automaticall discharged as thearmature is indexed. A ter hooking up the lead the winding machine wouldthen be revolved forward to approximatelythe position shown in Figure 1,when the wire may be engaged by the combination lead Skinner and setter47, one downward motion of which will pull the lower lead wire intoplace skin it and set it into the commutator slot, this device I preferto make as follows:

On 4the shaft 48 held by the brackets 49 and 50 I mount the quill 51 theright hand end of which is formed into the arm 52 carrfying the handle53 and the Skinning kni e of hook 54 the lead driver or setter 55 andthe line up hook 56 which may be sus ended on the spring 57 when theslots in t e commutator ear are cut to the working surface of thecommutator.

The edge of the combined hook or fork and Skinning knife, 54 ma be sharpand it may even be provided wit file surfaces on its interior 54 to aidin Skinning the wire, the working `surfaces of the line up hook 56should however, be smooth.

I prefer to spot the lead handler as I shall call this -device by theaid of a cam as l' 58 (which may be of any desirablev shape from a screwthread up) acting through t e follower 59 in this case shown as anadjust ing screw for adjusting the spotting point) arm 60 quill 51 etc.

, My lead setter and Skinner may be used as a hand tool if made withoutthe supporting members.

i By proportioning this device properly the wire will be caused to'slide through the hooks an amount suilicient to skin it at that partwhich should be inserted in the com-v mutator ear. l

I prefer to index the armature at this point; when the operations wouldbe repeated. p The indexing of the armature is done in a similar mannerto that disclosed in my application #453,363 using a dog 30 actingagainst' the teeth of the core except that I have" combined the indexingdog 3() (dotted) with the winding head so that the motion of the tailram 14 that releases and' resets winding heads also operates theindexing dog. I translate the linear motion of the ram into thetransverse motion required to index the armature by placing the mdexin'gdog 30 in such a position that the difference in the sine of the angleof the dog open and closed equals the number of' teeth it is de sired toindex. The locking key (not shown) requires no articulation in this con1bination. v l

Owing to the low friction ofthe armature bearings in the chuck 15 it isnecessary to provide brakes to prevent the drag of the indexing dogturning the armature backwards on'its recession. I do both this androvide a latch for securing the armature 1n the chuck or holder 15 bymeans of the latch springs 62 which I prefer to line with some frictionmaterial as leather, and to form with a decided retaining hump as shown,and to cause to press against any convenient portion of the armature asthe shaft or commutator.

In operation the multipolar type of this device the winding wire W islooped under and around the forming roller 63 which plays an extremelyimportant part. The first coil end, or lead is secured by any suitablemeans as to a commutator section as shown in Figure 1. Thewinding-position of the turret T1 is brought into position against thearmature and the machine revolved the proper number of turns, which willwind the wire into the first pair of slots. The upper lead is thencaught under the snubbing hook 45 by simply backing up the machine, andadvancing again to the position shown in Figure 1, when the lead setterand Skinner 47 are brought into play and the lead set as previouslydescribed. The winding head 16 and its appurtenances is then disengagedand reengaged during which process the armature will be automaticallyindexed by the indexing dog 30. The operations are repeated until thecoils which are all in the bottom of the slots have been wound in.

At this oint the -turret 1.6 should be revolved to t e next position T2,etc., which is adapted to winding the coils one side bottom, and theother side top of the slot, the o erations arethen repeated precisely asbe ore until all the slots have part of a coil therein. Then the turretshould again be revolved to osition Ta which is proportioned to put botsides of the coils in the top of the slots, and the, operation repeateduntil the completion of the armature exce t that it is possibly betterto throw back t e upper leads of theirst few coils winding the top coilsover the first coils and replacing these leads over the last coils oneat a time an operation that is facilitated by the fact that they are nowfree from the snubbing hook 45.

As previousl intimated the forms of this'invention s own nor the usesindicated are by no means the only ones which it may take or to which itma be put but they are deemed sufficient for the disclosure thereof.
